You are missing the start/end delimiters is your first problem...
Which ones? I've got the starter "^" and the closer "$", so what else
am I
missing?
You need delimiters around the regex, as stated in the documentation.
preg_match("/^ldap(s)?://[a-zA-Z0-9-]+\.[a-zA-Z.]{2,5}$/",$this->server)
This isn't going to work, the op has two forward slashes in the string that he is wanting to match with.
The op will need to use something other than forward slashes.
so, this is going to match:
ldap://testing123.com TRUE
ldap://www.testing-123.com FALSE
ldap://testing123.com.uk FALSE
ldap://testing123.or.us TRUE
preg_match('|^ldap(s)?://[a-zA-Z0-9-]+\.[a-zA-Z.]{2,5}$|', $this->server )
I also recommend using single quotes instead of double quotes here.
btw: why is there a period in the second pattern? Also, why are you allowing for uppercase letters
when the RFC's don't allow them?
Just my thoughts
Although you don't need to use slashes, you can use any character you
want but you must escape it in if it appears in the regex.
would a regex operation return false?
It would return false if your string doesn't match the expression.
The manual claims it will return a 0 signaling "0 matches found." And
then,
under "Return Values," it's says very quickly:
"*preg_match()* returns *FALSE* if an error occurred."
If it's not returning ANYTHING I'm assuming it's faulting, but the
calling
the error function returns 0 (kind've ironic, really...).
It will return false on an error, such as not having matching delimiters
aroung the regex.
The error function may retuyrn 0, but which of the following constants
is defined as 0?
PREG_NO_ERROR
PREG_INTERNAL_ERROR
PREG_BACKTRACK_LIMIT_ERROR
PREG_RECURSION_LIMIT_ERROR
PREG_BAD_UTF8_ERROR
